2018 GMC Sierra 1500 Denali

Listed by a franchise dealer in Morehead, KY · On lot for 4 days · VIN verifiable at NHTSA

This used 2018 GMC Sierra 1500 Denali is listed at $23,800 by Tim Short Auto Group in Morehead, KY 40351. It has 180,221 miles on the odometer (dealer-reported, not independently verified by OAV). The exterior color is Gray. It features a 4WD drivetrain with a 6.2L V8 engine and Automatic transmission.

OAV's independent, evidence-backed Price-to-Market analysis rates this vehicle as Fair Price — priced in line with the supported comparable range. Based on 129 comparable listings matched to this vehicle, the estimated market range is $14,199 to $37,082. These comparisons match year, make, and model, using trim where the data supports it. OAV does not adjust comparable prices for mileage — every price shown is the real advertised price. On used vehicles, mileage can still cause OAV to withhold a verdict — very high or unreliable mileage, or a lower price better explained by higher-than-typical mileage than by a genuine market discount — rather than call it a deal it can't support.

This vehicle has been on the lot for 4 days.

Analysis powered by OAV's patented inventory standardization technology (U.S. Patent No. 12,236,477). Verdict methodology ptm-verdict-v1 · snapshot Oct 14, 2026. The comparable band (patent pending) is the input; ptm-verdict-v1 is the versioned OAV rule set that turns it into this verdict.

Market context

This listing is part of OAV's broader Morehead, KY trucks market analysis. OAV rates each vehicle against its comparable range and comparable count — local-first, widening the comparison set only when local inventory is too thin to support a reliable range; days-on-lot and demand signals are shown separately, not as verdict inputs.

How this deal is rated

OAV compares this 2018 GMC Sierra 1500 Denali against similar vehicles currently available for sale — same make, model, and year range, using trim where the data supports it. OAV does not adjust comparable prices for mileage; on used vehicles it withholds a verdict when mileage would distort the comparison — very high or unreliable mileage, or a lower price better explained by higher-than-typical mileage than by a genuine market discount — rather than overstate a deal. Based on where this listing falls in that comparable set, it is rated:

• Great Deal — priced below the comparable-range floor by at least OAV's minimum-gap margin; a smaller gap under the floor is Fair Price.
• Fair Price — priced within the comparable range, or below the floor by less than that margin.
• Overpriced — priced above the comparable range.
• Unscored — OAV withholds a verdict when the evidence cannot support one: too few or too widely spread comparables, a price it cannot validate, a branded or salvage title, or mileage that would distort the comparison. The listing stays visible; only the rating is withheld.

Listings show OAV's Price-to-Market verdict and live market context for every dealer's inventory, whether or not the dealer has any relationship with OAV. Shopper questions reach dealers through OAV whether or not they have claimed their listings. A dealer that claims its listings can choose where those questions are delivered and read them in its OAV inbox; claiming changes nothing shown on any OAV page. A dealer that has received a shopper question through OAV has a green contact card; other dealers' cards are white. The color is not a rating, a verification, or an endorsement. A dealer that pays for OAV Dealer Plus has an "OAV Dealer Plus" label on the dealer contact block of its own listings. The label means the dealer pays OAV; it is not a rating, a verification, or an endorsement. That is the complete list of what a relationship with OAV changes. Payment never changes a vehicle's verdict, its eligibility to be scored or cited, the evidence shown or withheld, or where and how prominently the listing appears on any OAV page, board, or answer. There is no paid placement, ranking, ordering, verdict badge, or featured position of any kind. OAV sells dealers insight into the evidence, never influence over it.
